Abstract

Диспергатор для порошкового ингалятора содержит мундштук (10) с кольцевым каналом (12) для подачи потока частиц. Кольцевой канал имеет осевое входное отверстие (14) и осевое выходное отверстие (16), к которому примыкает кольцеобразная отклоняющая камера (18), в которой аксиально входящий поток частиц отклоняется преимущественно в радиальном направлении. К отклоняющей камере (18) в осевом направлении примыкает вращательная камера (20) с кругообразной периферийной стенкой (22) и осевым выходным отверстием (24).The dispersant for a powder inhaler contains a mouthpiece (10) with an annular channel (12) for supplying a stream of particles. The annular channel has an axial inlet (14) and an axial outlet (16), which is adjoined by an annular deflection chamber (18), in which the axially incoming particle flow is deflected mainly in the radial direction. A rotating chamber (20) with a circular peripheral wall (22) and an axial outlet (24) is adjacent to the deflection chamber (18) in the axial direction.
